Evaluating Stormwater Retrofit Potential to Reduce Flood Impacts and Improve Water Quality in Urban Coastal Plain Communities. Final Project Report Submitted to the Environmental Enhancement Grant Program, Grant Code: ECU021PRE1

This project developed an approach to identify unmapped stormwater control measures (dry detention basins or DDBs) in the City of Greenville, NC and evaluated a range of potential retrofit opportunities for a subset (34) of the DDBs that were identified. In addition, trash deposition, suspended sediments during storm events, and water levels were evaluated in a subset of DDBs and a range of educational activities were conducted to help enhance awareness of stormwater management challenges and potential solutions for Coastal Plain communities. Overall, a total of 214 DDBs were identified, and a geographical information system was developed that mapped these systems throughout the city.
